Topic:   Source Water


"NJAW's Investigation of Aquifer Storage and Recovery to Increase Swimming River Reservoir Safe Yield Without Reservoir Expansion"
Chad Kendra, NJ American Water; Theresa Landewe, INTERA, Inc.

New Jersey American Water (NJAW) provides water service to over 350,000 people in Ocean and Monmouth Counties. The Swimming River Treatment Plant has a reliable treatment capacity of 32.5 MGD and a permitted annual allocation of 9,125 MG (25 MGD average) from the Swimming River. The Swimming River supply varies significantly seasonally. In order to more effectively manage the supply, NJAW decided to evaluate the feasibility of using aquifer storage and recovery (ASR) to increase the safe yield of the system without reservoir expansion. Surface water would be treated and stored in the Middle PRM Aquifer during periods of excess availability for use during periods of lower flow. We will describe NJAW's successful, first-in-the-state application of the NJDEP/NJGWS safe yield guidance and will present the approach used to model the surface water and groundwater systems.

"Reservoir Management for Algae, Cyanobacteria, Cyanotoxin and TO Control"
Elizabeth Crafton, Hazen and Sawyer

There is an overall increasing trend in algal blooms, most notably cyanobacteria-dominated algal blooms. Many water supply systems are plagued by such blooms, which places an added burden on the water treatment plant and increases operational costs. In addition to addressing the biomass from elevated algal/cyanobacterial growth, secondary metabolites, such as, taste and odor compounds must also be accounted for and sufficiently removed in the treatment plant. Furthermore, a group of toxic secondary metabolites produced by cyanobacteria, cyanotoxins have elevated concerns due to required tracking of potential toxins. Addressing these issues requires a holistic multi-barrier approach that encompasses treatment process improvements, short-term management and long-term restoration of the source water system, and watershed management. The focus of this presentation will be on the source water component; it will outline both short- and long-term management techniques that can minimize the impact on the water treatment plant and reduce the risk of cyanotoxin presence, and long-term restoration techniques to prevent excessive growth and blooms.

Chad Kendra is a Planning Engineer at New Jersey American Water. He has been with the Engineering Department for the past 12 years and has worked on various short- and long-term comprehensive planning studies for both water and wastewater collection systems. Mr. Kendra's primary focus now is working within NJAW's Coastal North and Coastal South Operating areas. He is an experienced hydraulic modeler that provides recommendations and solutions for New Jersey American Water's capital projects program related to water supply water quality, and system distribution. He regularly supports, analyzes, and delivers alternative solutions for NJAW's Operations and Productions teams with issues related to water quality, storage, fire flow, optimization of different sources of supply, system growth opportunities, and overall delivery of water flow to the customer. Mr. Kendra holds a bachelor's degree in Civil
Engineering from Virginia Tech and has been a member of AWWA NJ for 10 years.

Theresa Landewe has nearly two decades of experience in water-supply development and water resources planning. Ms. Landewe's water-supply planning expertise has focused on regional and municipal level projects in which the utility and/or utilities needs to ensure an adequate and diverse water portfolio for the future. She has developed water-planning models, including a hydrologic model with GoldSim to determine future water supply deficiencies. She also has experience conducting groundwater-supply investigations, including collector-well feasibility studies, groundwater modeling for well-field development, and water-quality modeling to evaluate surface and groundwater interaction. Most recently she has been involved in dynamic hydrologic profiling of groundwater wells to determine zonal flow and geochemistry.

Elizabeth Crafton is a Source Water Quality Engineer with Hazen and Sawyer. Elizabeth assists utilities across the country by working to increase their source water quality and treatability. Her source water management approach encompasses both short- and long-term practices for a wide variety of issues. Elizabeth received her PhD from the University of Akron where she studied cyanobacteria and cyanobacteria-dominated harmful algal blooms. Her PhD research was funded by the Harmful Algal Bloom Research Initiative through the Ohio Sea Grant. During her PhD research, Elizabeth worked alongside a phycologist and botanist with over 40 years of experience who was also a contributing author for the commonly referenced Freshwater Algae of North America textbook. The duel advisement from both the civil engineering and biology departments provided Elizabeth with an interdisciplinary training and education, which makes her a unique asset for assisting with source water management.
